Nitrogen Special now $44.95.
Nitrogen will maintain a more constant tire pressure, saving you fuel and tire-maintenance costs. Humidity (water) is a bad thing to have inside a tire. Water, present as a vapor or even as a liquid in a tire, causes more of a pressure change with temperature swings than dry air does.
Filling tires with nitrogen involves filling and purging several times in succession, serially diluting the concentration of oxygen in the tire. This will also remove any water. There will be less moisture inside your tires, meaning less corrosion on your wheels.
